GENERAL STEEL CASTINGS CORPORATION,

RATION OF DELAWARE My invention relates to railway rollingstock andconsists in a novel locomotive structure, and more particularly in thenovel construction of the locomotive framing adjacent I therewith of theusual cylinder saddle.

The main object of my invention is to provide'for a shallow body centerplate thereby eliminating the overturning moment .in the center platewhich would be attained if a separate center plate were attacheddirectly to the underside of the cylinder casting. I attaken on the line66 of Figure 1.

tain this object by providing a locomotive underframing with sidemembers and relatively shallow transverse members between the sidemembers which are adapted to have a sepa-.

rate body center plate attached to the underside thereof, and preferablyabove the level of the bottoms of the side members.

Another object of my invention is to provide such side members andtransverse members with pads on their upper faces for sup porting thecylindersaddle casting or castings, thereby providing for very rigidconstruction and for thetransmission of vertical loads directly from thecylindersaddle casting to the transverse members and body center plate,without necessarily transferring the load through the side members.

It is a further object of my invention, in its preferred form, toprovide the vdesired structure in a one-piece locomotive frame or bedcasting so as to eliminate the labor and material necessary for securingseparately formed members to each other and to eliminate the possibilityof play between assembled members due to loosening of the securingmeans. Such structure also permits the most eflicient distribution ofmetal to secure required strength.

In the accompanying drawings which illustrate a selected embodiment ofmy inven-.

tion

saddle casting in section on a plane parallel with and contiguous to thecylinder saddle mounting surface on the side of the bed.

The left hand side of Fi ure 3 is a section taken on the line 33 ofFigure 2 and the right hand side of Figure 3 is a section taken Figure 4is a 'longitudinal vertical section taken on the line 44 of Figure 1.

Figure 5 is a bottom view of a longitudinal portion of the bedimmediately below the center plate mounting elements.

Figure 6 is a vertical transverse section The bed comprises parallelside members 1 each preferably constituting a box-shaped box-shaped incross section. The front end of the bed terminates. in a transversepilot beam 7 extending laterally of the side frames 1.

Parallel transverse members 8 connect side members 1 and preferably havetheir top surfaces 9 flush with the top surfaces of the saddle mountingpads 4 on the side members. These surfaces 9 also serve to engage thebottom of the cylinder saddle casting 10 and afford support for the samebetween the sides of the frame.

The bottoms of the transverse members 8 are located a substantialdistance above the level of the bottom of the side members and thebottom surfaces 20 serve to mount a body center plate 11 which willextend between the two transverse members 8 and will project downwardlytherefrom to engage a suitable truck center plate 12 and be connectedtherewith byvthe center pin 13. The bottom wall 6 of the underframe isprovided with an elongated recess 14 beneath the center plate carryingmembers 8 to accommodate the extension of the center plates across thelevel of the bottom of the frame.

I also desire to provide means for bracing and reinforcing the cylindersaddle casting at a point near its lower wall 10" and I show such meansin the form of a bracket 16 to.

which may be bolted the vertical flange 17 ,on the rear wall 18 of thecylinder saddle. This structure reduces the strain between the bottomand rear walls of the cylinder saddle.

The above structure attains, in a very simple and effective manner, theobjects set forth in the fore art of the specification. The engagementof the transverse members with the underside of the cylinder saddlepractically eliminates any upward deflection of the transverse membersdue to the thrust of the center plate, and the arrangement of thetransverse members is such that the holes 15 for the bolts for securingthe cylinders or cylinder saddle member can be reamed and the boltsapplied without interference.

' It is obvious that, in a structure of this type, many of the detailsmay be modified without departing from the essential features of thestructure and I contemplate the exclusive use of such variations indetail structure as come within the scope of my claims.

I claim:

1. In a locomotive, an underframe having side members, a cylinder saddlesupported thereon, a transverse member located between said membersbeneath said saddle, and a body casting, spaced transverse elementslocated betweensaid members and extending below the top thereof, and abody center plate mounted on the underside of said elements.

4. In a locomotive, a cylinder saddle casting, an underframe castinghaving side members adapted to support said cylinder saddle casting,spaced transverse elements extending between said members and locatedbelow the top thereof, and a body center plate mounted on the undersideof said elements and having upwardly extending elements engagingvertical faces on said transverse elements.

5. In -a locomotive, side frame members, a transverse frame memberextending between said" side frame members, and a'body center platemounted on the bottom of said trans verse member and at a higher levelthan the bottoms of said side members.

6. In a locomotive, side frame members, a cylinder saddle mounted onsaid side frame members and spanning the space between them, atransverse frame member connecting said side frame members below saidsaddle, and a center plate mounted on the bottom of said transversemember at a hi her level than the bottoms of said side mem ers. 7. In alocomotive, side framev members,

spaced transverse frame members extending.

jecting into said openin a body center plate supported on top of saidtruck center plate, and transverse members between the side walls ofsaid bed above said body center plate and carried on the same.

9. In a locomotive, a bed having a main portion of substantiallybox-shaped cross section provided with a substantial opening in itsbottom wall, a truck center plate projecting into said opening, a bodycenter plate supported on top of said truck center plate, transversemembers between the side walls of said bed above said body center plateand carried on the same, and a cylinder saddle carried on saidtransverse members in substantial vertical alignment'with theinterengaging portions of said center plates.

10. In a locomotive underframe casting,

. side members adapted to support a cylinder saddle casting appliedthereto, and a transverse member located between said side members andadapted forthe application of a body center plate to the undersidethereof.

11. In a locomotive underframe casting, side ,members adapted to supporta cylinder saddle casting, a transverse element located between saidmembers and below the top thereof, said element being adapted for theapplication of a bodycenter plate on the underside thereof.
